Radiation dose in multidetector row computed tomography cardiac imaging

Assessment of cardiac function using multidetector row computed tomography.

In patients with suspected or documented heart disease, a precise quantitative and qualitative assessment of cardiac function is critical for clinical diagnosis, risk stratification, management and prognosis. Cardiac CT is increasingly being used in diagnosis of coronary artery disease. Initially multi-detector row computed tomography (MDCT) was used chiefly for detecting coronary artery stenos...

Multidetector-Row Computed Tomography Coronary Angiography

onsiderable progress has recently been achieved in the field of noninvasive imaging of the coronary arteries by computed tomography (CT). Multidetector-row CT (MDCT) scanners are equipped with thinner detectors and have a shorter rotation time, which enables considerably faster volume coverage with a thinner slice width during a single breath hold. The entire heart volume can be covered with ne...

Noncardiac findings in cardiac imaging with multidetector computed tomography.

OBJECTIVES We investigated the frequency of the noncardiac findings in cardiac imaging with multidetector computed tomography (MDCT). BACKGROUND Multidetector computed tomography is an accepted new tool to evaluate the heart. In cardiac MDCT scans, organs other than the heart are also irradiated, but usually not assessed. METHODS A total of 503 patients underwent cardiac imaging with 16- or...

Multiple atrial septal defects in multidetector-row computed tomography.

A 70-year-old-man was referred to our hospital for percutaneous closure of a secundum atrial septal defect (ASD). His transthoracic echocardiography (TTE) showed 2 left-to-right ASDs with a pulmonary/systemic flow ratio (Q p/Q s) of 1.89 and normal left ventricular function. Cardiac computed tomography (CT) using 320-detector row CT (Aquilion ONE VISION edition, Toshiba Medical Systems, Tokyo, ...
